ANSWERS AND EXPLANATIONS




A) Ischemic stroke

This answer is incorrect.


The image shows bilateral lesions in the globus pallidus. This is characteristic of carbon monoxide poisoning, and would be unusual for ischemic stroke. Further, ischemic stroke would be unusual in this young patient.  (See References)

C) Ruptured cerebral aneurysm

This answer is incorrect.


The image shows bilateral lesions in the globus pallidus. This is characteristic of carbon monoxide poisoning. Bilateral pallidal aneurysms would be unlikely.  (See References)

D) Ethylene glycol

This answer is incorrect.


This image shows lesions in the globus pallidus bilaterally. Such lesions have been reported after acute ethylene glycol intoxication. However, the patient's presentation (e.g., red skin) are suggestive of another etiology.  (See References)

E) Parkinson disease

This answer is incorrect.


The image shows lesions in the globus pallidus bilaterally. This is not the typical lesion seen in Parkinson disease, nor is this young patient's history typical of Parkinson disease.  (See References)
